4.1.5 AC Input Voltage Requirements

4.1.5.1 AC Input Voltage Specification

The power supply operates within all specified limits over the input voltage range shown in the

following table. Harmonic distortion of up to 10% of the rated line voltage must not cause the

power supply to go out of specified limits. The power supply does power off if the AC input is

less than 75VAC +/-5VAC range. The power supply starts up if the AC input is greater than

85VAC +/-4VAC. Application of an input voltage below 85VAC does not cause damage to the

power supply, including a fuse blow.
